Stuart celebrated her 100th birthday on Sunday with more than 100 family members and friends, including Shirley MacLaine, Tom Arnold and Frances Fisher. Director James Cameron and his wife Suzy Amis hosted the fete at the Ace Gallery in Beverly Hills. Not there: Winslet or Leonardo DiCaprio.

Cameron, who is converting the 1997 Oscar-winning film into 3-D for re-release in April 2012, the 100th anniversary of the ship's sinking, told the Los Angeles Times: "Gloria's so alive, and her creativity, her artistry and the sparkle in her eyes is a challenge to all of us to live as fully and richly as she has and will continue to do as she heads into her 101st year."
